Patented Aug. 4, 1931 UNITED STATES JOHN A. PILCHER, OF ROANOKE,VIRGINIA SUPPORT FOR LOCOMOTIVE AIR PUMPS, ETC.

Application filed November 19, 1928. Serial No. 320,415.

My invention relates to certain improvements in frame supports which aresecured to the boilers of locomotives and which carry the air pumps orfeed water heater pumps or any of the other heavy devices on thelocomotive.

One object of my invention is to so fasten the support frame that it canbe so secured on the boiler of a locomotive or other object that it canbe adjusted and held in position after adjustment.

A further object of the invention is to provide one type of supportframe which can be used on different forms or types of boilers. it hasbeen the practice to design an air pump support for .each type ofboiler.

In the accompanying drawings:

Fig. 1 is a sectional view of a portion of the locomotive boiler showingmy improved support frame secured thereto; and

Fig. 2 is a face view of the support frame.

Fig. 3 shows another form of bracket 3.

l is a locomotive boiler having the ordinary lagging 2. Secured to theshell of the boiler is a bracket 3 having a base against the boiler andsecured to the boiler by the rows of studs marked 4 and 7. The row ofstuds marked 4 secure not only the bracket to the boiler but also securethe frame 5 for 0 supporting the air pump.

attached to it at the bottom a broad brace 10,

which is secured to a foot 8 of the pump supportframe 5 with a row ofbolts 9. The brace 10 is secured to the boiler with a row of studs 11.This brace 10, which is of considerable 4 width, rigidly holds the airpump support frame in position after it is once ad usted.

The studs or rivets attaching the bracket 3 to the boiler can be placedeither above or below or both above and below the line where the frame 5is attached to the bracket 3. It

is not even necessary to have the rivets or studs below the center lineif the broad foot is extended well below the center and well below thepoint where the bracket 3 is at- This to allow the bracket 3 to havesuch a base as to make it into the form of a bell crank in its actionand reducing the effect of the leverage a very narrow thimble would haveon a stud carried through straight on the line of the connection betweenthe frame 6 and the bracket 3 by the studs The cylinder of the air pumpor the device can be attached to this support frame either before orafter it is hung on the bracket.

lVith the above construction the brackets and air pump support framescan be kept in stock, and a bracket can be secured at any convenientposition on the locomotive so as to locate the air pump properly inposition. All that is necessary at the time is to cut the brace to theproper length.

By the use of this invention considerable time is saved in the erectingshop as all of the air pump support frames for the same pumps can beused on various types of boilers.

I claim:

The combination in a support for locomotive air pumps and the like of abracket arranged to be secured to the shell of the locomotive boiler, aframe suspended from the bracket and arranged to carry an air pump orthe like and a rigid brace securing the lower end of the frame to thebody of the boiler.

JOHN A. PILCHER.
